Streaked rattlepod (Crotalaria pallida)

Kuku renteng or streaked rattlepod or chique chique or giant striata (Crotalaria pallida) are flowering plant species in the Fabaceae family, annual perennial shrubs or short-lived, up to 1.5 m high with woody stems, hairy and have longitudinal grooves.

C. pallida has leaves with a trifoliate structure with 2-8.5 cm long stems, 3-13x2–5 cm wide and elliptical. Flowers are yellow or reddish brown and appear on stems 15-40 cm long, each of which consists of 20-30 flowers.

Fruits are pod shaped and measure 3-5x0.6-0.8 cm, each of which has 30-40 seeds that are heart shaped and measuring 3x2 mm, shiny and dark brown. The pods are green and brown when ripe, then dry and fall to carry water.

Kuku renteng grows wildly around rice fields, untreated lands and seasonal wet environments. This plant is favored by many flying insects including great eggfly (Hypolimnas bolina), chocolate grass yellow (Eurema sari), kismo bee (Xylocopa aestuans) and Javanese grasshopper (Valanga nigricornis).



Streaked rattlepod is widely used as ground cover and is processed as green manure. Flowers are eaten as vegetables and seeds baked to be used as a kind of coffee drink in Cambodia. Roots are chewed with areca nut in Vietnam.

C. pallida is also widely applied in traditional medicine to treat urinary problems and reduce fever, the roots are used to treat joint swelling and leaf extract to expel intestinal worms.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Broad sword fern (Nephrolepis biserrata)

Broad sword fern ( Nephrolepis biserrata ) is a species of fern in the Nephrolepidaceae, epiphytic and terrestrial, with grayish-brown stems, brown hairs, and 10–130 cm long. The leaf blades are green, 7 cm long, 1.5 cm wide, and hairy brown on the underside. The sori are attached to the underside of the leaf blade, with about 60 sori along the edge and are brown in color.

Whipple’s Cryptantha (Cryptantha whippleae), serpentine-adapted species endemic to northern California

NEWS - Whipple’s Cryptantha ( Cryptantha whippleae ) is described as a new species from a meandering barren area in the Shasta-Trinity National Forest in Siskiyou County, California, with one outlier population in a meandering area possibly in Lake County, California. Cryptantha is a genus of perennial herbs in the Boraginaceae (Amsinckiinae) and has been non-monophyletic in several molecular phylogenetic studies. It is currently recognized with 109 species and 124 minimum-ranked taxa, of which 63 are in North America and 47 are in South America, with one taxon found on both continents. Serpentine soils, particularly in northern California, are formed from ultramafic (meta-igneous) rocks that formed millions of years ago on the seafloor. These soils are very high in heavy metals (e.g., nickel, iron, and magnesium) and low in calcium and potassium. Serpentine soils are unsuitable for plants that have not evolved to tolerate the harsh conditions. Species that adapt to serpentines have h...
